Abstract

L'invention concerne des membranes céramiques à joints et support intégrés, ainsi que des piles électrochimiques et des empilements de piles associés. La membrane comprend une couche mince d'électrolyte supportée sur une couche d'électrode poreuse qui, à son tour, est supportée sur une couche de support céramique épaisse, de préférence, un support d'électrolyte céramique. La couche de support est divisée en une pluralité de zones membranaires minces autoporteuses par un réseau de nervures de support intégrées plus épaisses. La couche mince d'électrolyte et la couche de support céramique épaisse définissent de préférence un périmètre d'étanchéité entourant la couche d'électrode poreuse.
